A typical install, end-to-end
From your first call to a warm house, usually nine weeks.
No work starts without a written quote, a fully designed heat-loss survey, and a date you've agreed in writing. Below is what actually happens, on the actual days it happens.
Free in-home thermal survey
An engineer comes round, not a salesperson. Forty minutes. We measure radiators, take a U-value reading, and tell you whether a heat pump genuinely makes sense in your home.

Day 1One visit
MCS-grade heat-loss design
You get a full heat-loss model on paper. Recommended unit with sizing rationale, every radiator listed, labour and materials broken out, BUS grant deducted at the bottom.

You decide, in your own time
We don't follow up beyond one polite check-in. The quote is fixed for ninety days. If the answer is no, the answer is no — no chase, no discount drama.

Installation, our crew, our vans
Three to five days on site. Floors protected, new pipework run along structural lines, radiators swapped where the design requires it. Commissioned with thermal-imaging photos at handover.

Weeks 6–8Our team, never subbed
One-month tune, then we're behind you
We come back at four weeks to tune the weather-compensation curve to how you actually live. Then a seven-year workmanship guarantee and a real phone number — answered by someone who knows your install.

What sets us apart
The detail that other installers quietly skip.
Heat pumps fail because of bad design, not bad units. We over-spec at the survey, get the hydraulics right, and walk away from jobs we can't make work.
Approach
Designed-first installs, with the maths in writing.
You get the heat-loss model on paper. Every radiator, every pipe run, every °C of flow temperature.
Grant handling
£7.5k
BUS grant claimed for you. Off the invoice, not in your inbox.
Noise level
42dB
At 1m. Quieter than a fridge. Quieter than a polite conversation.
Hardware we know
Daikin, Mitsubishi, Vaillant.
Three brands we'd put in our own homes. No badge-engineered "premium" rebrands. We commission what we sell.
The crew
Our own engineers. Never subbed.
Six in-house engineers — no agency labour, no day-rate strangers in your kitchen. Their names are below, because they earned it.
The promise
If your system doesn't hit 3.2 SCOP in its first year, we re-engineer it at our cost.
The crew on your job
Four named engineers. No subcontractors.
Every install is designed, fitted and commissioned by one of these four. You'll meet two of them on the survey, the other two on the install. They're on the phone if anything's off, for seven years.

Recent install · Cobham, Surrey
12kW Ecodan · Jan 2026
1932 detached, oil to heat pump, four days on site.
Stephen and Carol's semi in Cobham had been on a tired oil system since they moved in. We designed a 12kW low-flow heat pump with five replacement radiators, kept their existing thermal cylinder, and integrated the Mitsubishi control with their existing Hive set-up.

Get in touch
Survey within the week. Heat pump by July.
Most enquiries we book a free survey for within four working days. Bigger properties we'd usually want a half-hour phone call first to talk through the existing setup. Either way, you'll get a straight answer about whether a heat pump is right for your home.
